ElasticSearch 2.2.0-ESIntegTestCase-在搜索中执行groovy脚本时出现ClassNotFoundException

Question

我一直在使用Elastic 1.4.4，但现在正在升级到2.2.0。 我无法运行集成测试。 我的集成测试扩展了org.elasticsearch.test.ESIntegTestCase ：

@ESIntegTestCase.ClusterScope(scope = ESIntegTestCase.Scope.SUITE, numDataNodes = 1)
public abstract class AbstractApplicationTest extends ESIntegTestCase {
  ...
}

我可以毫无问题地为文档建立索引，但是当我尝试使用脚本字段进行搜索时，出现错误。 我正在使用sbt运行测试（正在使用Play框架）。

我收到的错误如下：

{
    "error": {
        "root_cause": [{
            "type": "script_exception",
            "reason": "failed to compile groovy script"
        }],
        "type": "search_phase_execution_exception",
        "reason": "all shards failed",
        "phase": "query",
        "grouped": true,
        "failed_shards": [{

            "reason": {

                "caused_by": {

                    "caused_by": {
                        "type": "multiple_compilation_errors_exception",
                        "reason": "startup failed:\nCould not instantiate global transform class groovy.grape.GrabAnnotationTransformation specified at jar:file:/Users/ogg/.ivy2/cache/org.codehaus.groovy/groovy-all/jars/groovy-all-2.4.4-indy.jar!/META-INF/services/org.codehaus.groovy.transform.ASTTransformation  because of exception java.lang.ClassNotFoundException: groovy.grape.GrabAnnotationTransformation\n\nCould not instantiate global transform class org.codehaus.groovy.ast.builder.AstBuilderTransformation specified at jar:file:/Users/ogg/.ivy2/cache/org.codehaus.groovy/groovy-all/jars/groovy-all-2.4.4-indy.jar!/META-INF/services/org.codehaus.groovy.transform.ASTTransformation  because of exception java.lang.ClassNotFoundException: org.codehaus.groovy.ast.builder.AstBuilderTransformation\n\n2 errors\n"
                    }
                }
            }
        }]
    },
    "status": 500
}

我将重新格式化“ reason”消息以提高可读性：

startup failed:

Could not instantiate global transform class 
groovy.grape.GrabAnnotationTransformation 
specified at jar:file:/Users/ogg/.ivy2/cache/org.codehaus.groovy/groovy-all/jars/groovy-all-2.4.4-indy.jar!/META-INF/services/org.codehaus.groovy.transform.ASTTransformation  

because of exception 
java.lang.ClassNotFoundException: groovy.grape.GrabAnnotationTransformation

Could not instantiate global transform class 
org.codehaus.groovy.ast.builder.AstBuilderTransformation 
specified at jar:file:/Users/ogg/.ivy2/cache/org.codehaus.groovy/groovy-all/jars/groovy-all-2.4.4-indy.jar!/META-INF/services/org.codehaus.groovy.transform.ASTTransformation  

because of exception java.lang.ClassNotFoundException: org.codehaus.groovy.ast.builder.AstBuilderTransformation

是什么原因造成的？ 据我所知，我的类路径中有一个此类： org.codehaus.groovy.ast.builder.AstBuilderTransformation 。 我的build.sbt中具有以下依赖项：

  "org.codehaus.groovy" % "groovy-all" % "2.4.4",
  "com.carrotsearch.randomizedtesting" % "randomizedtesting-runner" % "2.3.0" % "test",
  "org.apache.lucene" % "lucene-test-framework" % "5.4.1",
  "org.elasticsearch" % "elasticsearch" % "2.2.0" % "test" classifier "tests" withSources(),
  "org.elasticsearch" % "elasticsearch" % "2.2.0" withSources(),
  "org.elasticsearch.plugin" % "analysis-icu" % "2.2.0" % "test",
  "org.elasticsearch.module" % "lang-groovy" % "2.2.0" % "test"

...并且我的EsIntegTestCase扩展类中包含以下内容：

@Override
protected Settings nodeSettings(int nodeOrdinal) {
    return Settings.settingsBuilder()
            .put(super.nodeSettings(nodeOrdinal))
            .put(IndexMetaData.SETTING_NUMBER_OF_SHARDS, 1)
            .put(IndexMetaData.SETTING_NUMBER_OF_REPLICAS, 1)
            .put(Node.HTTP_ENABLED, true)
            .put("script.groovy.sandbox.enabled", true)
            .put("script.engine.groovy.inline.search", true)
            .put("script.engine.groovy.inline.update", "true")
            .put("script.inline", true)
            .put("script.update", true)
            .put("script.indexed", true)
            .put("script.default_lang", "groovy")
            .build();
}

@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
    return pluginList(GroovyPlugin.class, AnalysisICUPlugin.class);
}

我完全陷入困境，Google不愿意提供帮助！ ：slightly_smiling：

任何帮助或指针将不胜感激。

非常感谢，OGG

现在解决了。

问题实际上是，这是一个SecurityException，被重新抛出为ClassNotFoundException。

按照https://www.elastic.co/guide/zh-CN/elasticsearch/reference/current/modules-scripting-security.html上的说明，我创建了一个安全策略文件并为以下类别添加了权限：

grant {
    permission org.elasticsearch.script.ClassPermission "java.lang.Class";
    permission org.elasticsearch.script.ClassPermission "org.codehaus.groovy.*";
    permission org.elasticsearch.script.ClassPermission "groovy.*";
    permission org.elasticsearch.script.ClassPermission "java.lang.*";
    permission org.elasticsearch.script.ClassPermission "java.util.*";
    permission org.elasticsearch.script.ClassPermission "java.math.BigDecimal";
    permission org.elasticsearch.script.ClassPermission "org.joda.time.*";
};

然后，我开始在命令行中通过我的安全策略文件进行测试：

-Djava.security.policy=security.policy
